To all whom it may concern:

EDWARD W HARDEN, and MICHAEL DEMPsEY, citizens of the United States, re-

siding at Hamilton, infthe-county of Butler and State of Ohio, haveinvented certain new and useful Improvements in Railway-Frogs,

of which the following isaspeciflcation.

It is the object ofour invention to provide a new and im rovedrailwayfrog in'which: the arts whic would benormallysubjected to t egreatest wear from side-contact as well as pounding blows from thewheels of the vehicle passing thereover, shall becomposed of hard metal,for instance, hardened steel,

and so arranged that the continuity of the" tracks shall not beinterfered with and so.

connected with the regular trackage that danger of derangement isavoided, and an improved construction provided, and it is the furtherobject of our invention to so combine and arrange theconstructionmentioned that the j ointsin the frog-and preferably alsobetween thefrog andthe continuation'of the trackagemay be protected from poundingstress; and theinvention will be readily understood from the followingdescription and claims, and from the drawings, in which latter: I

vFigure '1 is a plan viewof our improved rallway frog. Flg. 2 isavertical cross-section of the same on the line zz'of Fig. 1. Fig. 3 isaverticalcross-section of the same on the line yy of Fig. 1. Fig. 4-. isa verti-- cal cross-section ofthe same on the line 00-41:

of Fig. 1; and, Fig. 5 is a vertical cross-section of the same ontheline w w of Fig. 1. j

A B O D represent stub-rails as part of the frog, between the inner ends0f which'thei block E of the frog is located. This block,

' isof hard metal, for instance, hardened steel,

and for convenience we shall hereinafter refer to the sameas thehard-block. Ordinary continuation-rails]? GHQI of the'trackage arearranged to abut and be secured to the outer ends of the stub-rails, theouter ends of the said continuationrails being shown broken away. i

K and L are reinforce-rails at the outer portionsof the frog and in theform shown also act as riser-rails at thetoe endof the frog as shown atk 'l, and as wing or guard rails at the heel-end of the frog as shown atthrough the same.

j I g I I I jecting opposite the point, as shown at n, Be 1t known thatwe, WILLIAM H. RABBE,"

shown beveled," so thatthe joints p p may be i at an angle to the rotaryaxes of the wheels passing thereover. Bolts 10 pass through the parts. i'3 The point-part'of the hard-block is preferably spearesha ed,comprising the head Q and the shank ig, which latter at its outer orheel-end is formed with a riser-face g, the

rest of the spear-sha ed point-part however being preferably of theheight of the rails so that the wheels may ride thereon and be su portedthereby. The inner ends of the stu rails A- B are shown beveled at theirinner faces'asat a b, the shank also forming afillingblock between saidstub-rails. Bolts 20 pass The hard-block as shown also comprises outerwalls n 11?, shown as continuations of the sidegage-faces N N, betweenwhich and the toe the grooves R R for accommodating the flanges of theWheels are located. The reinforce-rails are at their in ner facesprovided with tapering recesses k Z for accommodating the side walls n nof I the hard-block, the hard-block adjacent said side walls also formina filling block between said reinforce-rails, olts 30 securin the artstogether. At the toe-end of said ardblock the reinforce-rails arerespectively provided with slight curves k Z which, being slight andlong, may be formed without drawing the temper from the rails, and atthe heel-end of said hard-block they are provided with a spreading bend76* Z for forming the wings 76 Z or-guard-rails, it being understoodthat these reinforce-rails at their heel-ends do not serve as supportingrails for the wheels but as guard-rails acting sidewardly against theflanges of the Wheels for directing said flangesproperly intothe groovesR R.

"Filling b o'cks S S are located between the Wing-ends of saidreinforce-rails and the heel of said hard-block preferably s anning thejoints a 1) between said hard-b ock and the stub-rails A B, bolts 40holding the parts in place.

It will be noted that in our improved construction we provide a hardenedwheel-supporting block against which the ends of the parted to them inmanufacture which is destroyed upon the heating of the rails for thepurpose of so bending the same. We avoid this objection in our improvedconstruction and further provide a frog in which the joints areprotected by riser-rails, and in our im proved construction we furtherprotect the joints between the toe-ends of the stub-rails of the frogand the continuation-rails of the trackage joining therewith, by acombined riser and reinforce-rail, providing an especially strong andsafe construction.

It will be understood that the riser portions of our improved frog actupon the outer portions of the treads of the wheels which are usually inpractice of slightly greater diameter than those portions of the treadsadjacent to the flanges of said wheels, owing to the wear which inpractice takes place upon railway Wheels adjacent to said flangesoccasioned by ridin on the regular trackage of the railway.Filling-blocks S S are shown between the rails C K and the rails D L.

It is of course obvious that changes may be made from the constructionherein shown and described without departing from the spirit or scope ofour invention.

Having thus fully described our invention what we claim as new anddesire to secure by Letters Patent is:

1. A railway frog comprising a hard-block having a point thereon and acombined riser, reinforce and guard-rail at the side thereof saidlast-named rail having a downwardly sloping riser-face at its riser-end.

2. A railway frog comprising a hard-block provided with a point andopposing gagefaces adjacent thereto and a reinforce-rail at each side ofsaid hard-block constructed as a riser-rail at its toe-end and as awing-rail at its heel-end, each of said reinforce-rails having adownwardly sloping riser-face at its riser-end.

3. In combination, in a railway frog, a hard-block having a point andgage-face walls thereon, said gage-face walls extending beyond saidpoint past the point of greatest convergence between said gage-facewalls at the throat of said block, rails whose inner ends abut againstsaid gage-face walls, and reinforce-rails spanning the oint between saidfirst-named rails and gage-face walls, substantially as described.
